Type of reaction : Synthesis or combination reaction
Further explanation
Given
Reaction
Zn + O2 = ZnO
Required
Type of reaction
Solution
There are several types of reactions that can occur
Synthesis: 2 or more elements(reactants/compounds) combine to form a single product
The general formula :
A + B ⇒AB
The above reaction has not been balanced
The balanced reaction is
2Zn + O2 → 2ZnO
